Abstract Carbon assimilation is a crucial part of the photosynthetic process, wherein inorganic carbon, typically in form CO 2 , converted into organic compounds by living organisms, including plants, algae, and subset bacteria. Although several carbon fixation pathways have been elucidated, Calvin–Benson–Bassham (CBB) cycle remains fundamental to metabolism, playing pivotal role biosynthesis starch sucrose cyanobacteria. However, Ribulose‐1,5‐bisphosphate carboxylase/oxygenase (RuBisCO), key carboxylase enzyme CBB cycle, exhibits low kinetic efficiency, substrate specificity, high temperature sensitivity, all which potential limit flux through this pathway. Consequently, RuBisCO needs be present at very concentrations, one factors contributing its status as most prevalent protein on Earth. Numerous attempts made optimize catalytic efficiency thereby promote plant growth. Furthermore, limitations process highlight benefits engineering or discovering more efficient mechanisms, either improving itself introducing alternative pathways. Here, we review advances artificial engineering, integration synthetic biology, genetic metabolic pathway optimization, intelligence order create plants capable performing photosynthesis. We additionally provide perspective current challenges solutions alongside personal opinion promising future directions emerging field.

Abstract Photosynthesis—the conversion of energy from sunlight into chemical energy—is essential for life on Earth. Yet there is much we do not understand about photosynthetic a fundamental level: how it evolved and the extent its diversity, dynamics, all components connections involved in regulation. In this commentary, researchers working aspects photosynthesis including light-dependent reactions, photorespiration, C4 metabolism pose discuss what they view as most compelling open questions their areas research.

ABSTRACT In C 3 plants, photorespiration is an energy expensive pathway that competes with photosynthetic CO 2 assimilation and releases into the atmosphere, potentially reducing plant productivity by 20%–50%. Consequently, flux through has been recognized as a major way to improve crop carbon fixation productivity. While current research efforts in engineering are mainly based on modification of chloroplast glycolate metabolic steps, only limited studies have explored optimizations other photorespiratory steps. Here, we engineered imGS bypass within rice mitochondria glycine toward betaine, thereby, improving rice. The transgenic plants exhibited significant accumulation reduced photorespiration, elevated photosynthesis photosynthate levels. Additionally, introduction leads increase number branches grains per panicle which may be related cytokinin gibberellin signaling pathways. Taken together, these results suggest diverting mitochondrial from betaine synthesis can effectively enhance architecture rice, offering promising strategy for developing functional bypasses potential

As a grain and oil crop, soybean presents much lower yield than other staple crops. However, crop yields can be improved by applying modern agricultural technology, such as diethylaminoethyl hexanoate (DA-6) mepiquat chloride (MC), which are important plant-growth regulators that substantially affect growth yield. This study examined the effects of DA-6 (30, 60, or 90 mg L−1) MC (100, 200, 400 on growth, development, root structure, photosynthetic physiology, osmotic regulation, via field pot experiments. The results showed effectively promoted increased parameters plant height, leaf area, dry weight in different stages 21.0%, 18.7%, 66.4%, respectively.
